Vedran Vucic is in Dalj (near Vukovar, Croatia), Milankovic’s birthplace, today for the birthday celebrations. He says that the house in which Milankovic grew up has been renovated for the occasion. I am assuming it has been turned into a museum. As I will go to Serbia again this summer, perhaps Vedran and I can take a trip to Dalj, where a group of science popularizers are interested in hearing about Open Access publishing, science blogging and other developments in science communication.
